Actor Mia Farrow's paraplegic son Thaddeus Wilk Farrow, who was found seriously wounded in his vehicle in Roxbury, Connecticut, on Wednesday, had shot himself fatally, the state medical examiner concluded during autopsy on Thursday. Connecticut Police ruled out any criminal angle to the 27-year-old's death. He was declared dead at a hospital, AP reported.

She said in a statement on Twitter that the family was devastated by the loss. "He was a wonderful, courageous person who overcame so much hardship in his short life. We miss him. Thank you for the outpouring of condolences and words of kindness," she added.

Mia Farrow, who is known for her roles in movies like Rosemary's Baby, The Great Gatsby and Death on the Nile, had adopted Thaddeus in the mid-1990s from Kolkata, where he had contracted polio and was paralysed from the waist down. The actor is a child polio survivor herself. Thaddeus had worked with his mother in an international summit on polio eradication at the United Nations in New York.
